BALL-BEARING.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed February 21, 1911. Serial No. 610,029.

To all whom it may concern:

Be it known that I, HpNRY I'IESS, a citizen of the United'States, residing at Philadelphia, in the county of Philadelphia and State-of Pennsylvania, have invented certain new and useful Improvements in Ball- Bearings, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to ball bearings and more particularly to that class thereof provided with continuous and uninterrupted tracks or ways which offer no impediment or obstruction to the travel of the halls thereon, and whereby the several parts are held in assembled relations, thus constituting a bearing of the unit-handling type. The present improvement contemplates the provision of the bearing with certain additional featureswhich facilitate the asse1nblage and also possess other advantages as will hereafter appear. Bearings of the unit handling type and provided with uninterrupted tracks, are assembled in various ways, among which may be mentioned the employment of eccentric dis lacemcnt according to the well known onrad invention. This procedure, namely, eccentric displacement, is ordinarily followed for the introduction of substantially less than the full complement of balls, after which, if additional ones are desired. they may he inserted by other means, such as non-full depth tillin o )euin s in the rin and the like.

My present invention, however. contemplates the complete assemblage of all the halls at one time or of the balls individually, and this even in the case of a full type bearing where the raceway is entirely or almost filled with halls. To this end, I pro ride on at least one of the rings at the side of its track or way. a circumferentially extending tapered surface. which facilitates the passage-of the balls into the raceway between the rings, and in connection with this tapered surface, I provide the ring with a filling opening extending through the ring between its side edges, which opening communicates with the space between the tapered surface and the surface of the 0p posing ring, so that the balls may be assembled in proximity to the tapered surface preparatory to their being forced thereover into the raceway.

faces extending entirely around the rin at the inner sides respectively of the all tracks thereon, and forming a circumferential space between the ball tracks, the filling opening in the ring extending through the same and leading to such circumferential space. It is to he understood, however, that but one tapered surface may be employed, and further that such surface need not extend entirely around the ring the es sential feature of the invention in this connection being the provision, in connection with a tapered circumfeientially extending surface at the side of the ball track, of'a filling opening for the halls which extends entirely through the ring and in proximity to the tapered surface. In cases where the tapered surface extends entirely around the ring, the halls may be introduced one at a time through the filling opening and the entire series assembled against the tapered surface, whereupon the whole series may be forced as a unit ovei the tapered surface and seated at one operation in the adjoining raceway. If, on the other hand, the tapered surface extends only partially around the ring. or, in other words. in a circumferential direction. then a portion only of the complete series may he forced into the race way by one operation after having been assembled adjacent the tapered surfaces. Or. again. the balls may he forced individually and in succession over the tapered.

surfaces. and this whether the tapered surface is continuous or only partially so.

In the accompanying drawings: Figure 1 is a longitudinal section through a twoserics ball bearing. having my invention embodied therein. Fig. 2 is a similar view showin how the balls of the first series are assemhfi troduction into the raceway. Fig. 3 is a similar view showing the first series of balls in place in the raceway, and the second serice in position primaratoryto being forced into its raceway. liig. 4 is a. plan view of d preparatory to their forced in-,

the bearing showing the filling openings. Fig. 1s a perspective view of the inner surface of one of the rings showing the form and relation of the tapered surfaces.

Referring to the drawings; In the par ticular form illustrated in the drawings, the bearing comprises an onierd-ing '1. an inner ring 2 formed respectively with iw'o Illllllterriiptcd tracks or ways 1. and l" and 9f and 2*, forming between the rings two raccways, in which are twoseries of balls A and B. One of the rings, the outer ring 1 in the present instance, is provided at the inner sides of its tracks, with two circumferentially extending surfaces 3 and 4, which are tapered or sloped in opposite .directions, forming a circumferential groove in the ring midway between its ball tracks;

v I e 4 Q and formingin connection with the ad acent surface of the opposing ring, a circumfer- 'entialspace 5 extending continuously thereedges of the sloping surfaces.

around. The outer edges of the sloping surfaces terminate a considerable distance iiitral or deepest line of the tracks, and some distance inward in a radial direction of the deepest portion ofthe tracks, thus consti-' tilting in effect ribs 6 and 7 at the inner sides of the two series of hallsrespectively whereby the parts are held in proper operative relations after they areassembled.

Extending radially through the outer ring and leading into the circumferential space 5, is a fillin'gope ing 8 circular in cross-section and of a' (i the balls to kit passed one at a time freely theretlirough,..the outer edges of th e filling opening at diametrically opposite sides terminating'bn a line coincident with the outer In assembling the balls in their raceways. they may be introduced individually into their respective raceways by forcing them in succession over the shoulders at the sides of the'tracks or ways after having been first passed through the radial filling opening. A more speedy procedure, however, is to force the entire series as a unit into its raceway. This may be accomplished by first introducing the balls of one series in succession through'the filling opening and assembling them as shown' in Fig. 2 in the circumferential space 5 and against the tapered surface "at the side of the raceway in which the. balls are to be'assembled. By

means of a suitably formed tool introduced between the rings from the opposite side,

. the entire-row'of balls may be forced to the left and overt-he sloping surface 3 into its raceway, as shown in F ig. 3. The other series of balls' is now introduced through I the filling opening and assembled in the circumferential space and against the sloping surface 4'at therighaas in Fig. 3, and by a suitable tool, or. a series of tools,' which may.

iameter to permit any particular form or construction of the parts except in so far as such limitations are specified in the claims. I

Having thus described my invention, what I claim is i 1. In a ball bearing,t he combination of inner and outer rings, each formed with a continuous and uninterrupted track or way forming a raceway, and the balls mounted therein; one of said rings being provided at one side of its track or' way with a circunr ferentially extending inclined or tapered surface forming in connection with the opposing ring, a circumferential groove for the temporary assemblage of balls preparatory to their being forced over the inclined surface into said raceway, and the said ring being provided. withv a filling opening extending entirely through the same in a d'i-- rection transverse to the axis of the r ng and leading to the said circumferential 5 groove; whereby the balls introduced through the filling opening may be assembled on the circumferential inclined surface and then forced thereover into the raceway.

In a ball bearing, the-combination of the-inner -and outer rings, each formed with a continuous and uninterrupted track orway forming a raceway, and the balls inount'ed' therein, the outer ring being provided at one'.side of its track or way with a circumferentiallyf extending inclined or gtapered surface. forming in connection with the inner ring, a circumferential groove for :the temporary assemblage of balls preparatory to their being forced over the inclined .110

surface into the raceway, and-the said outer ring being provided with a filling opening extending entirely therethrough' in a direction transverse to the axis of the ring and leading to the said circumferential groove; .115

whereby the balls introduced through the filling opening maybe assembled on the circumferential inclined surface'and then forced th'ereover into the raceway.
